INTRODUCTION General Information WARNING These fireplaces are conventional heat circulating appliances with standard grates, outside combustion air kit and standard decorative glass doors. The BCD36MH model is fitted with a blower and is available as an option for model BC36MH. The grate included properly positions the fire and limits the amount of fuel. IF A REPLACEMENT GRATE IS NEEDED REPLACE THE GRATE WITH MODEL 87L20 ONLY.
WARNING Insulate Joists Same As Ceiling Do not obstruct the collar openings around the base of the chimney at the top of the fireplace. Do not insulate the chimney enclosure cavity with blown or fill type insulation materials.

ASSEMBLY STEPS Note: The following steps represent the normal sequence of installation. Each installation is unique, however, and might require a different sequence. 1. Position firebox prior to framing or into prepared framing. 2. Install the chimney system. 3. Connect house wiring to the fireplace for blower (blower is optional for model BC36MH). 4. Install the outside combustion air kit. 5. Plumb gas line if a decorative gas appliance will be used.

Step 4. Fireplace should be secured to side framing members using the full length nailing tabs at the top and bottom of the fireplace front face. Use screws, 8d nails or equivalent fasteners (Figure 13). This manufactured home model is also provided with floor brackets used to secure the fireplace to the floor to prevent shifting in transit. Note: The use of floor brackets are optional. They are included (unbent) inside the Combustion Air Kit package, located inside the firebox.
WARNING Do not allow insulating materials to be blown into the space inside the thimble and the chimney. To do so could result in a fire hazard. Outer Pipe Of Chimney Outer pipe section installs in just the opposite way; the lanced end goes down and each new section goes OVER the outside of the previous section installed (Figure 20).
Step 7. Secure flashing by nailing along the perimeter into roof using 8d nails or equivalent fasteners. If shingled roof, slide upper end and sides of roof flashing under shingles (trim if necessary), seal the top and both sides of the flashing to the roof with roof caulking. Cover fastener heads with roof caulking (Figure 24). Note: If chimney extends more than 8' above roof surface, guy wires are also recommended.
FTF8 CHIMNEY COMPONENT CALCULATIONS The minimum installed height of the completed fireplace system is 10' 6". The maximum height is 40' 0" when the chimney is exposed. To determine the number of chimney sections and chimney components required, follow these steps: 1. Determine total vertical height of the fireplace installation. This dimension is the distance from the surface the fireplace sets on to the point where smoke exits from the termination. 2.

Offset Elbow Assembly IMPORTANT Offset elbows install the same as chimney sections. First, snap the inner section INTO the preceding inner section of flue. Check connection by pulling up slightly to ensure a tight fit. Next, the outer sections snap lock OVER the preceding outer section of chimney. Again, check outer section by pulling up slightly to ensure proper connection is made.
Always check local building codes. Installation of the BFK36 Blower Kit must comply with local regulations as well as the National Electric Code. Combustion Air Actuator When using the decorative gas appliance, the fireplace damper must be set in the fully open position. Combustion Air Kits These appliances are equipped with an outside (make-up) air door and integral actuator arm and an outside air kit with a collar, duct and hood (90L83).
Note: A 1" air space must be preserved for all combustible materials extending for any continuous length adjacent to the chimney. FIREPLACE FINISHES Hearth Extensions and Wall Shields Mantels and Trim It is especially important to insulate between the studs of an outside chase cavity and under the floor if the floor is above ground level. Do not place insulation directly against the fireplace or chimney system.
Wall Shield Required Where Less Than 12". Adjacent Wall Is Never Allowed Closer Than 7".

Calculating Minimum Thickness if Multiple Materials are Used At times it is important to know what combination of materials are acceptable for use as floor protection. The “R values” are used to determine acceptable combinations of materials because “R values” are additive where r and k values are not.
